Lmn .lonx 5i bind, residing .iti'jhclmsiord, Ewen, England have inhim-s for Liquid-Fuel Burners, of which the foili'iwing is =1 Qpt'C'iiHFaliOH.

This invention relates to regulators for liquid fuel burners anti has for im object to construct a device that .-.hall he prompt. and curtain in its action part 'nlarly when used in conjunct on with a steam gen or heat.- ed by a humor of this type.

According to thin; invention the movement necessary in control the. humor is obtained by the cooperation or {5 the coznbincil effect. of temperature mil prmiure of the mntcm: m the generator. The means by which the desircrl end is accomplished are such that the temperaprimsure cooperate to affect. the complcte r'onirol ne any with a steam generator wherein the fiucluuiu of temperature and pressure are such that both rapid and steady action on the pan; of the regulator are ncceamry to effect corresponding. regulation in the supply of heat to the generator.

According to one construction of this inv'ontion, a '25 single expzm'sihle tube i disposed across the hot. n of Lin.- gcnt-mlor above the burner, the tube being carried in such a way that the llL'dL will not distort its support ing frame. One end of the tub is connected to a hollow srni onflry support and at its free end the tube carrie it pin which rests against the love: or other inc-r zJI- .lz'll. whose movement is imparted 1/0 the means for controlling the burner. The leve is conveni ntly provided with 1W0 arum one of which is engaged by the pin already mentioned, the other being in engagement with a second pin. This pin is connected to a spring controlled piston which is adapted to me vc in achamber to which 'ihe contents of the generator have access. .he 1" "sure within the generator acts on the piston to force 1 pin outwards and operate one arm of the lev r 40mm] the cxpunsion of theiuhe under the influence of the l(-'-{m.:lllru of the generator contents also acts to operate the other arm of the lever, the control of the burner bring thus obtained by the combined effect of temperature and pressure of the generator contents. The um :um of expansion of the R'tmight tube may be inrr::1.-:( a! .n the following wayz-A straight tube of convvni-z-rit lmgtli and i'orim-r'l of =.uiiabl-:- metal having a niodemte coi'flii-i-nt of expansion has one end secured in :he union in which the inlet steam pipe is armchcd. liLl oi'ihe lnl i. therefore relatively fixed.

The strain in 15km: off from the outer H'i-l of the third tzibc which also currir-s the pin actuating be c mml mechanisrn. The telescopic arrangement of the thr e tubes is such that :he effecl of singlc long tube of expansihlc metal is obtain-e l.

The construction of the regulator may vary considerably in accordance \nih the purlmflvfl for whi h it is to he used and the typrs of gencratorhnd burner with which it is to be combined.

Reicrring to the dnuvings:-Figum l is a. uerrtienal view of a. conztruction emp oying three tubular members armngml concentrically. Fig. 2 is an elevation partly in section of a. modification.

Likc letters indicate like parts throughout the draw-- CUCilll'lUlll of expansi n of which is negligible. This tube A* is joiner: :1: its corresponding and to the ire. end of the tube A and at its oppo-iic *h'l to the neighhcring end of the tube A' in this manner a telescopic tube is plUYHlG-Ll. At its other end the tube A has screwed m it a box A to which the steam outlet pipe A is connected. The steam enters the boil which mpports the tube A through a pipe A and after passing through the ube is withdrawn by the pipe A On the and of the map A is the pint, the body of which is formed integral with the cap, as Shown. the pin being provided with an wljustable head, and need in conjunction with a control device such as will be dcscribu with ref rence to Fig. i. to operate the burner.

{oierring now to Pi 2, a single expnngible till-e A is comic-uteri at one eml to a hollow stationary Suppor A and at iis free end carries the pin sliding in a bearing in .he bracket D. The lever liin this in; is provided ith two arms E E of which the arm E is pres-50d against by the pin C, while the arm E projects downward and is engage by a pin i. This pin if is connect d to a piston (F adapted to more in :1 ch C and the chamber (-ornnnmicatcs by a pipc- G with the contents of the gencrator. The Incum within the generator, therefore, act-1 on the rear end of the piston against the action of a spring C to force. the pin outward and operate the lever 1-1. The h-w-r can thus be operated by the xpansion of the llllll A under the influence of the tempcnitnrc of the gcm-mior contents and by the preesnre within thc generator acting upon the pist n ('onvcnit-ntly the generator (-ontcms are conveyed in ibe free end of the tube by a sin! ionary iube A and after pun-dug along said tube about. an inner tube A which extends to within a short distance amb r- What '0 vluizu ac-i uur inv mi u null lumein :wruru in nr gzilutlng dwiie I'm :1 liquid t'm-l lmrhm', in! niblnuiinu with :1 Mi 4 hat-(rank h n-r and .m up (:rxiiiw uunm- 'tiun lu um: zirm ufi th. lI-vcr :imi [h-s burn. -r|:;:ul:iiiu: duviev, wt :1 tubular expnnslhlu mcinlv'r l0 whirh (he uuntnnh' u[ the genemtnr hunted by U- burner have (w-(aw, 21 lived hearing for unzmul nt' tlw lulm. :1 Supp -l! for the mh r ml u! the tube, uwuns win-why the (IIIIHHHS of tlugenerator have acre in Um v means for transmitting umvcnwnt.
